SSIS Custom Component, Output Buffer Problem

Hi Guys,

I created a SSIS custom component, transformation (Asynchronous) with one Input collection and 2 output collections.

The SSIS Package which includes the Component I created works well in the Business Intelligence Studio, but when the same Package is run in the 'Execute Package utility' It fails to run. ( when you Double click on the dtsx file)

The cause of the failiure is

public override void PrimeOutput(int outputs, int[] outputIDs, PipelineBuffer[] buffers)

method receives only one output buffer when executed using the 'Execute Package Utility' { outputs = 1 , buffer.Length = 1 } ( when executed in the BI studio, the method receives parameters of both the output buffers that I expect { outputs = 2 , buffer.Length = 2 } )

The property ComponentMetaData.OutputCollection.Count = 2 as well. Yet the PrimeOutput method provides only 1 buffer.

The Validation Succeeds on both instances, which I assume means that Meta Data is Provided Properly.


What would be the reason for the same pakage to run in 2 different ways like this,

What might I have missed out to do, to make the package run in different ways on 'Business Intelligence Studio' and 'Execute Package Utility'

Thanks a lot



Below are some of the lines from the ProvideComonentProperties Method which deals with the output Collection, Isn't this sufficient for the PrimeOutput to provide 2 output buffers?





ProvideComponentProperties()









public override void ProvideComponentProperties()
{

RemoveAllInputsOutputsAndCustomProperties();
base.RemoveAllInputsOutputsAndCustomProperties();
base.ProvideComponentProperties();

//other function calls

IDTSOutput90 output1 = ComponentMetaData.OutputCollection[0];
output1.Name = "Output1";
output1.Description = ".......................";
extracted.SynchronousInputID =0;


IDTSOutput90 output2 = ComponentMetaData.OutputCollection.New();
output2.Name = "Output2";
output2.Description = "..........................";
output2.SynchronousInputID = 0;

//other function calls
}
